Filed: 1987-02-02
Abstract: PURPOSE:To permit the optimum dwell control in correspondence with the number of engine revolution even in the case when a computer fails, by installing a back-up circuit having a dwell controller in the control unit of an engine controller. CONSTITUTION:When a microcomputer 1 in an engine control unit is in a fail state, a trouble detecting circuit 2 outputs an instruction for selecting output signals supplied from a back-up circuit 9 for a signal selecting circuit 4.
